Critic Reviews for The Scientist

I like that the story on the Island is really impacting the story in the present. And I love that we are hearing more and more about Ra's Al Ghul!

From its inhumanly strong antagonist to its tales of mysterious domestic tornadoes with the power to fling people 20 blocks from home, this is an episode that's out to test the boundaries of the show.

Feb 7, 2019 | Rating: 3.5/5 | Full Review…

So far, seeing the show leave the ground a little bit has resulted in some fun and exciting stories that have been surprisingly well crafted.

"The Scientist" largely succeeds in launching 'Arrow' to a higher form of superhero storytelling, though not without a bit of seeming clumsiness.

Aug 6, 2018 | Full Review…

With all these subplots struggling for screen time, one gets the feeling that there are far too many balls in the air to truly connect with any of them on an emotional level.

Aug 2, 2018 | Rating: 7.2/10 | Full Review…

Even though Barry isn't quite Barry, the dynamic between him and Oliver was fantastic and I'm sorry we won't get much more of it.

It's little things like these that Arrow should be actively working not to do. It's doubly frustrating that it has, actually, managed to avoid these issues for a nice chunk of the season, until the past few episodes had characters acting just to move.

"The Scientist"...makes that doe-eyed dork [Barry Allen] absolutely irresistible.

Aug 2, 2018 | Full Review…

The first clash between Ollie and a super-powered foe was exciting without breaking the more grounded tone of this series.

Aug 1, 2018 | Rating: 8.5/10 | Full Review…

Deftly dealing with the dicey issue of implementing superpowers into the 'real world' and introducing a DC icon with flair, it's a superb outing for Arrow.

Aug 1, 2018 | Rating: 5/5 | Full Review…

["The Scientist"] is so good that it makes up for some of the (many) sins of the previous episode...even though it has to address the immediate aftermath of it.

Aug 1, 2018 | Rating: 4.5/5 | Full Review…

While the arrival of Barry Allen...from Central City to Starling City was not exactly unexpected...some other more obscure characters continue to pop up in ways that should please hardcore comics fans.
